Hi all,
I am writing a graphical editor in GEF which basically draws
several function lines which are composed of individual straight
line segments (modeled by connections between the two adjacent
function points). In addition, some of those line segments are given a
label describing them.
My problem is that I have to layout those labels in such a way that
(whenever possible):
- the individual labels do not overlap with each other
- the individual labels do not overlap with the individual line
segments
To me, it seems as if I need some sort of global layout algorithm
which decides where to place the individual labels. As this seems
to be non-trivial, I wanted to ask whether GEF itself has any support
for this kind of "optimal" layout arrangement or whether there is some
other library which addresses this issue?
I hope my explanation is clear enough and I would very much
appreciate any feedback. Thanks a lot in advance!
Regards,
Ovidio
